I would recommend the Swampfox kingslayer, Life time warranty and comes in green circle dot which stands out better to me. You can also get the sight in red circle dot or just red dot. There are no battery cap issues with the kingslayer as it just comes in and out of a compartment on the side. I changed my battery yesterday in about 20 seconds, doesn't change poi at all as the sight doesn't have to be moved off the gun to do it. Great sight , weighs 1 ounce and hasn't failed me yet. My son also uses one and loves it. It also has 10 adjustments , no issues ever seeing it, and automatic shut off after 4 hours if you forget to turn it off. Take a look and see what you think, great customer service if you have any questions for them. Good luck in your set up! Oh and absolutely 0 wrong with the Burris if you already have it as far as seeing the sight, I have a Nikon Spur which is similar in red dot and have no issues. Just pointing out the Swampfox comes in green circle dot which does seem to show up better for me. You will love the size of a sight like this!
